Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid hardware configurations are used in existing multi-axis control systems, then system stability is maintained, but design freedom and versatility are reduced
Solution Approach 1:
The controller is divided into multiple independent control function circuits, each capable of performing specific control functions. These circuits can be independently configured and connected through standardized interfaces, allowing flexible system design without requiring rigid hardware configurations. Each circuit can be customized for specific control tasks while maintaining overall system stability through standardized communication protocols.
Solution Approach 2:
The control function circuits are designed with universal standardized interfaces that enable them to perform multiple control functions. By using standardized signal transmission protocols and interface specifications, the same circuit architecture can be applied to different control applications, significantly improving design freedom and versatility while reducing the need for custom hardware designs.
2Adaptability or versatility
If multiple independent control function circuits are used, then versatility and design freedom are improved, but system complexity increases
Solution Approach 1:
Standardized interfaces act as intermediaries between independent control function circuits, providing a uniform method for signal transmission and data exchange. These standardized protocols simplify the integration process by establishing clear communication rules, reducing the complexity of connecting multiple independent circuits while maintaining their individual functionality and versatility.
3Adaptability or versatility
If customized control units are implemented, then compatibility among units is improved, but manufacturing complexity increases
Solution Approach 1:
The control function circuits are designed with configurable parameters that can be adjusted to match different control requirements. By changing software parameters, communication protocols, and interface configurations rather than physical hardware, customized control units can be manufactured using standard production processes, improving compatibility while maintaining ease of manufacture.
